Pa/vzqw A r TOPNEY Patented Dec. 29, 1953 INTERLOEKING snINGLn l -r d B.- Boneone ilin wepd Application April 5, 1949, Serial No. 85,63.8 .3 fi nl new) -1 The present invention relates to a newand proved form of interlocking shingle and more particularly to an improvement over the shingle disclosed in my, prior Patent i l-136,326, issued October 25, 194 9.

e n le discl se in. t e a oresaid patent r is particularly adaptable :to shingles formed of metal :but is .of such construct on that it ca no made o c pos materia f ie .adyaniaeos of a metal shingle have lon be n. nown bu d -to high costs ,has been little used. The primary object of the present invention is {to provide a m tal shing hi h ,can .b manufactured at .a relativel low cost, vcomparable :to av -oomposition i e e and y t embody al .o the advan a es of a metal shingle with numerous advantages not previously shown vor contemplated.

As pointed out in my patent, shingles of the interlocking .type are generally formed by extending he slot iowarelvi r m itheed 0f the shingle to define the locking tabs and the co- ,operating locking slots. 'lhis results in a number of imperfect shingles due to the fact, that the tabs are easily bent or torn during theassembly operation or after the shingles have been :interlocked.

Thisdefect is overcome bythe shingle of the instant case and the pending case by having the slots forming the locking tabs and the,cooperating locking slots wholly within the confines of the shingle, the edge of the shingle being left continuous and uninterrupted.

In the present invention, the shingle is formed of metal and preferably of aluminum. The use of aluminum renders the shingle somewhat flexible and in order to reinforce the shingle, I have provided a novel integral rib arrangement which not only serves to reinforce the shingle but acts to interlock the shingles in such manner as to form a rigid shingle assembly. The novel rib arrangement also serves to permit the circulation of air within the shingles and yet prevent side lash from rain or wind or the seepage of rain beneath the shingles.

A further feature of the present invention is the provision of a metal shingle capable of being formed from sheet metal by a single stamping operation thereby resulting in economy of manufacture. The novel construction is such that the shingles can be assembled with a minimum amount of labor and when applied to a roof presents a most attractive appearance.

Other objects and advantages of the invention will be apparent in the following detailed description taken in connection with the accompanying drawing, wherein 2 Fie r l i ame tier o a pneterre m iodi: me it o th shinee io mins th sub ect matter of the present invention; V

erally rectangular confi uration a cons itutes :slightly ofisetl from ,the plane of the shingle ,by

ofisettinga small "portion .of the-shin le durin :the stamping. operation, 1 said offset portion being indica-tedsbythe, numeralQl-i: Attheline formed by this offset portion 25, a pair of slots I5 are stamped out of the metal shingle and constitute the locking slots. The locking tabs I6 are formed by cutting U-shaped slots in the shingle as indicated by numeral ll. The locking tabs I6 are one inch in Width and the slots I5 are approximately one inch and one sixteenth wide in order to readily receive the locking tabs.

As seen in Figure 1, a pair of holes l8 are cut out of the shingle adjacent the slots [5 for receiving the usual hall 23 for attaching the shingle to a roof. An additional nail hole I9 is provided midway of the shingle adjacent the edge [2 for properly lining up the shingles during the roof assembly as will more clearly appear as the description proceeds.

In order to insure against side lash and to increase the rigidity of the shingle, the shingle is provided with a pair of parallel upstanding ribs ,formed in the shingle during the stamping opaee gozse 20 and 2| for added rigidity and further serves as a rain stop as will be pointed out below.

The flange I4 is provided substantially midway the length thereof with a cut-out portion 24 to receive the rib 2| as seen in Figures 5 and 6. As seen in Figure 6, the height of the cut-out portion 24 is equal to the height of the rib 2| in order that the portion of the flange M to the right of the rib comes in close contact with the shingle below the flange. This is indicated in Figure 6 by numeral 28. The three overlapping shingles being referred to in this figure are indicated by numerals 2Q, 30 and 3|. As seen in Figure 7, that portion of the flange H of the shingle 3| to the left of rib 2| and closely adjacent the rib is slightly spaced from the underlying shingle 30, as indicated at 21. This space is equivalent to the thickness of a shingle and results from an overlapping of the shingles at this point. The function of this space is to provide an air circulation opening as will be pointed out below.

The shingles may be assembled in interlocked relationship in the manner shown in Figures 2 to 5 wherein the numeral 22 denotes the usual wooden roof member to which the shingles are applied. In assembling the shingles, the shingles are laid from left to right beginning at the lower left hand corner of the roof. The first shingle is laid and nails 23 driven through the holes I8. The next adjacent shingle is then applied by pressing down on locking tabs l6 and inserting said tabs through slots I5. When the overlying shingle is pushed to the right with the rib 2| overlying the rib 20, the second shingle is secured to the roof by driving nails into the second set of holes |8 of the overlapping shingle. This operation is continued until the lower row of shingles is assembled.

The first shingle of the second row is applied by juxtaposing its lower hole |8 over hole IQ of the first row shingle and continuing the assembly as previously explained. The provision of hole l9 thus insures the proper positioning of the second row of shingles. All of the rows of shingles may be assembled in a similar manner.

As seen in Figure 5, the air aperture 27 permits air to enter below the shingle and thereby enables air circulation within the shingles. The flange l4 acts as a rain breaker and any seepage 4 of rain below flange l4 will be blocked by the rib 26.

Although the present embodiment of the invention is illustrated in connection with roofing shingles, it will be readily apparent that the present invention may also be applied to siding shingles.

It will be noted that the construction herein shown and described is well adapted to accomplish the objects of the present invention. It will be understood that minor changes may be made in the present invention without departing from the spirit thereof. Therefore, I do not wish to be limited precisely to the construction herein shown except as may be required by the appended claims considered with reference to the prior art.

I claim:

1. An interlocking shingle comprising a body portion of general rectangular configuration having a forward edge, transverse edges and a rear edge, a portion of the shingle adjacent said forward edge being upwardly offset, locking slots formed at the juncture of said ofiset portion and the remainder of the shingle, cooperating locking tabs formed in the body of the shingle adjacent the rear edge and spaced inwardly of the edges of the shingle, and ribs extending across the shingle parallel to the forward edge.

2. An interlocking shingle as defined in claim 1, and a down-turned flange at the lower transverse edge of the shingle, said flange having a notch therein to receive one of the parallel ribs.

3. An interlocking shingle as defined in claim 2, said notch being of the same height as the height of the parallel ribs.
